摘要
Abstract
The influence of water temperature on the distribution of seepage field in fractured rock mass is a hot issue of research on rock mass hydraulics problems .On the analysis basis of effect of water tempera-ture on fissure water flow mechanism , the paper established the mathematical model of rock fracture seep-age field considering the influence of water temperature and solved numerically by using the finite element method.The results show that the value of water head by considering the influence of water temperature is higher than that of not considering the influence of water temperature;the influence of water temperature on hydraulic conductivity plays a leading role in the process of water temperature; the larger the fissure width, the more obvious influence of water temperature on fracture seepage field .关键词
